SEALHLOCK.

SPECIFICATION forming peut of Letters Patent No. 399,526, dated March 12, 1889.

Application tiled September 1, 1888. Serial No. 284,348. (No model.)

To all whom it may concern.-

Be it known that I, MICHAEL (l. HARNEY, of the City of St. Louis, in the State of Missouri, have invented a certain new and uset'ul Improvement: in Seal-Looks, of which the following is a t'nll, clear, and exaet description, reference being had to the accompanying drawings, forming part ot this specification, and in whioh* Figure I is a side elevation ot' my improved seal-look, showing it applied to a door of a railway-ear. Fig. II is a side elevation ofthe seal. Fig. III is a similar View of the springeateh. Ifig. lV is an enlarged side elevation ot the bolt and springand'seetion ot' the seal. li`ig. Y represents a modification ot' the seal. Fig. YI represents another modification of same. l `ig. `VII is a Inoditieation ot' the spring.

My invention relates to an improved seal, intended more particularly t'or use in securing the doors ot' railway-ears; and Iny invention Consists in [features ot' novelty hereinafter l'ully deserilrod, and pointed ont in the claims.

tetorring to the drawings, l represents the door-trame ot' a ear, and 2 the door.

2) represents a hasp secured to the door, and which tits over a staple, i, seeuretfl to the frame.

5 represents a bolt that may be secured to the trame or body of the ear by means of a ehain, (t. The upper end of this bolt is pret'- erably provided with a shoulder, 7, that prevents the bolt from moving downwardly out of the staple, and the lower end ot the boltis preferably formed in hook shape, with an upturned end, S. On this end ot' the bolt is a head, t), formed with a shoulder, l0, which would be made by an annular groove, l1, in the bolt beneath-the head.

l represents a spring, Consisting, preferably,of a thin plate of metal havingintnrned ends This spring tits over the head 9 ot the bolt, as shown in Fig. IV.

1l represents a seal that tits over the head Q and over the spring l2, as shown in Fig. IV, and it has a shoulder, l5, at the upper end ot a neck, llf. The lower extremities, 17,

of the spring fit against the shoulders l5 of the seal; (when the seal is applied as shown in Fig. 1V,) and the upper extremities of the points 13 tit against the shoulder lO ot' the head 9.

In applying the seal the bolt is first in serted through the staple i after the hasp has been put on. Then the spring is plaeed over the head 9, and then the seal is placed over the spring and held to the bolt, as shown in Fig. IV. It will be seen that after the seal has been applied it will be impossible to get it oft' without destroying it, as the spring holds it firmly in pla-ee. The seal is of sutlicient size to be incapable of passing through the staple 4, so that the bolt cannot be taken out ot' the staple without removing the seal. The seal is made ot glass, elay, pottery, poree lain, or other fragile material, so that it may be easily broken by authorized persons.

In l` `ig. Y, I have shown a di Herent-shaped seal, where the edges are made circular and the sides fiat, and in Fig. YI is still another modieation, wherein iour wings, 20, are used, and in Fig. VII, I have shown a Inoditieation ot the spring, where tour arms (instead of two, as shown in Figs. III and IV) are employed.

I have described the looking spring placed over the head ot' the boltprevious to its insertion within the seal; but when desired the spring may be previously plaeed within the seal and the point of the pin be Inade to engage with itas it is inserted in said seal.

I elaiin as my invention l. In a seal look, the combination of a bolt having a head forming a shoulder, a spring having ends fitting beneath the head of the bolt, and a seal having` a shoulder engaging' against the extremities of the spring', substantially as and for the purpose set forth.

2. In a seal-look, the combination of the bolt formed with a hook or upturned end, a head on the end of the bolt, a spring having ends engaging beneath the head ot the bolt, and a seal fitting over the head of the bolt and having' a shoulder engaging the extremities ot' the spring, substantially as set fort-h.
